Abstract
A developing device that attaches/detaches to/from a main body of an image forming apparatus includes a photosensitive drum, a charging roller to rotate while contacting the photosensitive drum to charge a surface of the photosensitive drum to a uniform potential, and a separating member to rotate between a first position where the charging roller is separated from the photosensitive drum and a second position where the charging roller contacts the photosensitive drum. The separating member includes a body into which a rotary shaft of the charging roller is inserted to be rotatable, and a contact portion extending from the body and contacting the surface of the photosensitive drum when the separating member is located at the first position so as to separate the charging roller from the photosensitive drum, wherein the contact portion includes a friction member including rubber.
